Opinion: Sasuke had the best curse seal.

[NinjutsuSeeker]

Sasuke's curse seal gave him wings which in a real battle is a major advantage to be able to fly. Other chracters can fly by riding stuff but only a few other characters can fly all on their own like oonoki but he sucks anyway. imagine sasuke flying and sniping with susano arrows.

the runner up i think is kimmaros because he got a tail but he could prolly make a bone tail anyway so his curse mark was useless

Sasuke had the gayiest curse seal I ever seen. He looked like a emo drag queen with hands on his back. Wtf, lip stick and some diamond on his nose. man that was the wackist powerup kishi ever gave anyone. all the other curse mark users had awesome transformations...not sasuke.,.
